- We (DPM & MLP) successfully set up a federated database with two “autonomous partitions” spanning RCF and the counting house.
- An autonomous partition is a part of the federation which is independent from other partitions.
- It has its own lock server
- It has its own host machine(s)
- In normal running, the partitioning is invisible (unless you want to know).
- In case of a failure, the partitions will continue to function for processes only accessing data within one partition
- This is the case for most DAQ processes (run control, etc), so if RCF is down, it won’t affect the data taking (and vice versa, but when are our machines ever down?)
It’s a major step forward towards doing away with a lot of ASCII-based configuration files.
